Lesson DELIVERY

Introduction
I will state to my students what the objectives for today are, they will have to write them on their interactive science notebook in a Cornell note style.
I will start my class by asking students to tell me what they know about DNA? And where they heard it from?
Links of concepts to students' experience





Have you seen forensic evidence or any movies


that mentions DNA? Why you think DNA is so important?


















Procedure
I will use an LCD Projector in order to use the DNA Interactive Timeline website. Students will have time to take accurate notes of the lessons.
Next students are going to play a puzzle game using the chemical bases Adenine, Cytosine, Guanine and Thymine.
For this section we are going to use the second website and we are going to enter the section Build a DNA Chain.
Students are going to have an opportunity to come to the computer and add a section of the chain.

Closure
Quickly we will review what they learned during the lesson about DNA. I will refer back to the objectives provided at the beginning of the lesson.
I will let them know what we will be learning next. For that we will use the third interactive website in which students will have the opportunity to extract DNA in an interactive laboratory in which they will be doing the extraction.
I will reserve the computer lab for the next lesson so that each student can enjoy the interactive laboratory to the full capacity.

Assessment
I will assess students by using the Red Robin strategy, using a plush toy tossing it around while asking students to tell me what they learned today.
